STS-48/STS-12/STS-3 Section Parameters 9
The following STS-48, STS-12 and STS-3 section parameters are monitored:
â– Section (B1) Coding Violations (CV-S): To monitor the performance of an
STS-48, STS-12 or STS-3 section, the section B1 parity is calculated,
written, and checked for errors. The section B1 parity violation counter is
incremented for each section error detected.
â– Section (B1) Errored Seconds (ES-S): An errored second (ES) is a
second in which there are one or more B1 parity violations detected, one or
more LOS defects, or one or more LOF defects.
â– Section (B1) Severely Errored Seconds (SES-S): A severely errored
second (SES) is a second in which there are 249 or more B1 parity
violations detected, one or more LOS defects, or one or more LOF defects.
â– Section (B1) Severely Errored Frame Seconds (SEFS-S): A section
severely errored frame second (SEFS) is the number of seconds during
which an out-of-frame event occurred.
A threshold crossing alert (TCA) is generated if an STS-48 or STS-3 section
parameter exceeds the provisionable threshold. The generation of TCAs can be
enabled or disabled using the PERFORMANCE-Set-PM Threshold-Section
input.
